[Mediawiki-l] User rights questions: the dash, and $wgAddGroups

18 May 2008

I have two questions about user rights:

1. For blocking read access to the wiki:

$wgGroupPermissions['*']['read'] = false;

I frequently see people recommend a $wgWhitelistRead array like this:

$wgWhitelistRead = array(
 'Main Page',
 'Special:Userlogin',
 '-'
);

What does the '-' entry mean?

2. Is the documentation on $wgAddGroups outdated, as stated here,
under "Obsolete instructions for 1.13?":
